Because of high remanence, high coercivity and high magnetic energy
product, neodymium magnets are widely used for servo motor, stepper
motor, linear motor, etc.
For the quality of the electric motor magnet,ketian focus on the following
ten point:1)Dimension;2）Appearance ; 3)Magnetic moment; 4)Demagnetization curve;
5)Irreversible loss ; 6)Corrosion; 7)Mechanical property; 8)Glue ;9)Subassembly;
Most customers require neodymium motor magnets with high maximum
working temperature, such as 35SH, 38SH, 35EH, 35UH, use some small
arc magnets to form a ring magnet, magnetization direction is through
diameter, NS and SN. And some require other shapes such as segment,
wedge shape, block, ring, or special shape.
